Question

Programming 4_1: Create a class call CellPhone. This class represents a cell phone. The data a cellphone should contains: manufact- the name of the phone’s manufacturer; model – the phone’s model number; retailPrice – the phone’s retail price. The class will have the following methods: 1)A constructor that accepts arguments for manufacturer, model number, and retail price. 2)A setManufact method that accepts an argument for the manufacturer. This method will allow us to change the value of manufact field after the object has been created, if necessary. 3)A setModel method that accepts an argument for the model number. This method will allow us to change the value of model field after the object has been created, if necessary. 3)A setRetailPrice method that accepts an argument for the retail price. This method will allow us to change the value of retailPrice field after the object has been created, if necessary. 4)A getManufact method that returns the phon’s manufacturer. 5) A getModel method that returns the phone’s model number. 6)A getRetailPrice methos that returns the phone’s retail price. Create a second tester class call CellPhoneTester with a main method.  Create an Apple iphone with model number F2LQQ6KVGRX3, retail price $599.  Change the retail price to $399.  Get the current retail price by calling the method of the iphone. You can test your method by creating a few other cellphones, and calling more methods from main method.

Answer 1

import java.util.*;

class CellPhone
{
String manfName;
String modelNo;
double price;

CellPhone(String nm,String no,double p)
{
setManufact(nm);
setModel(no);
setRetailPrice(p);
}

void setManufact(String nm)
{
manfName=nm;
}

void setModel(String no)
{
modelNo=no;
}

void setRetailPrice(double p)
{
price=p;
}

String getManufact()
{
return manfName;
}

String getModel()
{
return modelNo;
}

double getRetailPrice()
{
return price;
}

}

class CellPhoneTester
{
public static void main(String args[])
{
CellPhone cp=new CellPhone("Apple_iPhone","F2LQQ6KVGRX3",599);
System.out.println("\n\nThe name of the phone's manufacturer : "+cp.getManufact());
System.out.println("\nThe phone's model number : "+cp.getModel());
System.out.println("\nThe phone's retail price : $"+cp.getRetailPrice());
cp.setRetailPrice(399);
System.out.println("\nThe current retail price : $"+cp.getRetailPrice());
System.out.println("\n");
}
}
